How do I configure wpa_supplicant.conf for WPS push-button? I'm building an IOT device, powered by headless Debain on a CHIP (< and will have connectivity to a customer's wifi. I'm trying to build in functionality for wifi connectivity to the customer's router in a way that wouldn't require the customer to ever need to input a password and username. Basically, I'd like to have WPS push-button functionality in Unix. I've installed `wpa_cli`, and have been tinkering around with wpa_supplicant.conf. However I'm very confused. The example `.conf` document located here , states that we'd need to input all the parameters of the router ahead of time. Why would that ever need to be the case? Doesn't that defeat the purpose of WPS (i.e. WPS should be blind to any access points and should handshake with the nearest router that has its WPS window open)?

Edit your `/etc/wpa_supplicant.conf` configuration file as follow:

At least you need to add the following line :


ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1
CONFIG_DRIVER_NL80211=y


You can enable some others support:


ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1
CONFIG_DRIVER_NL80211=y
CONFIG_WPS=y
CONFIG_WPS2=y
CONFIG_WPS_ER=y
CONFIG_WPS_NFC=y
uuid=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx


Get the `uuid` through `status` command from `wpa_cli`

To connect

1. run `wpa_cli`
2. From the Interactive mode, run `wps_pbc` and push the `wps` button.
3. Once connected run `dhclient wlan0` (change `wlan0` with your interface wifi)
